Default Early Blight on Toms

For the last two years since moving to Wessex during the wet summers my
toms failed due to late blight.
So this year I grew them in pots against a south-facing wall. So after
all the recent rain I now have early blight. Lower leaves going yellow
with black spots.

However, the toms in one of those simple £14.99 4-shelf patio cloches so
far unaffected despite it being wide open to the rain at the front.

Think I'll give toms a miss next year.


It's now at least my 8th year of saying that. There's really nothing
you can do, but it is a bit early for blight. Are you sure that's what
it is? Are there any brown patches on the stems?
Lower leaves turning yellow could be due to drying out in pots. Even
with rain, toms in pots need extra watering.
If it is blight, well hard luck and as you say, with all this wet
weather, we don't stand much chance of avoiding it.
Any one else affected?

I too think it's a bit early for blight, it shows as darkbrown/black patches
on leaves and stems and it's usually the top leaves that show the signs
first. Within a few days the plant turns black and is dead.
We grow blight resistant varieties and I've proved to my satisfaction they
actually are resistant, they do show signs of blight eventually, after all
the others are well dead, but it doesn't seem to spread through the plant.

Ferline, Fantasio and Legend are the three we are growing this year.

May not be the best tasting, although they aren't bad, but better any
home-grown tomato than none.

I've also be considering building a tent of plastic over my rows of Toms,
just enough to stop the rain getting on the leaves should be all that is
required. Anyone else tried that?
